i'm not sure i understand what you're doing onAttributeChange
I am attempting to save the attribute on every change because the save was not working.
why write the feature to JSON?
To be honest with you this came from the update manger, not to sure.
why load both the editor widget and the attribute inspector?
are you confident that your implementation of the undomanager isn't causing the problem?
I tried the editor widget first, it didn't function the way I was wanting it to.(It still did not update the feature). The editor widget is commented out now, but I left the code there just in case I wanted to use it later. I can take the undomanager out it is not nessacary right now.
a good way to check would be to try updating the feature without the callback
I can try this to.
Just a note the service was down for a little bit. My feature class is a Point Z shape style so I added a default value for the Z to the service. It is up now. Thanks for all the great info.
